Application filed March 18, 1901. Serial No. 51,811. (No model.) I

steam-engines of the type designed to be employed with steam motor-vehicles.

Our invention consists in the combination, with an engine, of a lubricating-case in which the engine is inclosed.

The objects of our invention are a construction of inclosing casing which will protect the engine against dust and moisture and form a receptacle within which a body of oil may be maintained and which will act to lubricate the engine by its own movement, and, further, a device for freeing the interior of the oil-case from any condensed water.

The accompanying drawings will serve to illustrate our invention, 'in which Figure 1 is a top view of the engine, its support, and inclosing casing, the engine, airpump, and water-pump being shown partially in elevation and partially in section and the inclosing casing with its top broken away and a portion of its sides in section. Fig. 2 is a side viewtaken on the line 2 2 of Fig. 1, showing the engine, air-pump, and waterpump valves in elevation with the inclosing casing in section. Fig. 3 is a section taken on the line 3 3 of Fig. 1, showing a portion of the engine and water-pump in elevation. This view also shows a section through the body of a motor-vehicle. Fig. 4 is a perspective View looking downward from the right and showing the construction of the engine-frame, position ofair and water pumps in the frame, &c. Fig. 5 is a perspective View of the crankshaft eccentric and sprocket-gear, taken from above and to the right. Fig. 6 is a section through the inclosing casing, air-pump and its valve, water-pump and its connections, taken on the line 6 6 of Fig. 1. Fig. 7 is a plan view and partial section taken on the line 7 7 of Fig. 6. Fig. 8 is a partial elevation and section of the casing, taken on the line 8 8 of Fig. 6. Figs. 9 and 10 are respectively a sec- 'met-al.

tion and plan view through that portion of the casing where a rod which operates the reversing-lever enters the casing.

In the drawings, 10 represents the cylinders, of which there are two; 11, valve-chest located between the cylinders; 12, engine-pistons; 13, piston-rods; 14, crank-shaft; 15, ee-

centrics on crank-shaft; 16, balanced cranks on the ends of crank-shaft; 17, sprocket gear.

The crank-shaft, eccentrics, cranks, and sprocket-gear are formed from one piece, of We prefer this construction, for the reason that where the parts are formed of a single piece of metal there can be no slipping of any of the parts upon the shaft, and hence the necessity of frequent inspection and adjustment avoided. We consider this point one of great practical importance in motorvehicles designed to be operated and cared for by'unskilled persons.

The crank-shaft 14 is mounted in the bearings 18, which are rigidly secured in position by means of two pairs of parallel rods 19 20. These rods are secured at their upper ends to the cylinders 10 and at their lower ends to these bearings. The rods 19 and 20 of each pair are secured together by a K-brace 21.

22 indicates rods arranged parallel to the rods 19 20 and secured at their upper ends to the cylinders 10 and at their lower ends to forgings 23, secured to the ends of a transverse brace 24..

By reason of the arrangement of rods and braces described a very rigid and light frame is obtained for the working parts of the en girls and one in which the strains are resisted in straight lines, and, further, a con struction is obtained which permits of the frame being readily taken apart for inspection and repair. V

The rods 19 22 are parallel and occupy the same plane, and threading these rods are the movable cross-heads 25, which form a bearing and point of attachment for the pistonrods 13 and connecting-rods 26.

27 indicates the usual eccentric-rods, connected to the reversing-links 28 and through the valve-rods 29 with the slide-valves 30.

31 indicates a lever through which the links 28 may have their positions altered to change the direction of movement of the on gine, as is well understood in engines of this description.

- Carried by the forgings 23 on opposite sides of the engine-frame is'an air-pump 32 and water-pump 33. The pistons 34 of these pumps are pivotally connected to the cross-heads 25, and hence correspond in movement with that of the engine-pistons.

Formed as a part of the bottom of the bearings 18 for the crank-shaft 14 are the exten-= sions 35, to which is bolted the transverse bar 36. Pivoted in this bar is a bail 37. The bar 36 has hearings on its ends 38 for the links 39, which support the lower end of the engine. The links 39 are pivoted to the body of the "ehicle 40 at 41. The opposite end of the engine has secured to the cylinders strap-bearings 42, which take over a horizontally-disposed bar 43, connected to the links 44, pivoted to the vehicle-body at 45.

46 is an adjustable distance-rod interposed between the bail 37 and a fixed portion of the vehicle-body 47.

The general features of construction of the engine as describedthat is to say, a twocylinder link-motion oscillating slide-valve engine-present no points of novelty, and such we do not claim. We, however, con- "sider the construction of the frame as set is situated at the top and has its points of support beneath a vehicle-body, preferably elastically supported on suitable springs, as is common wit-h vehicle-bodies, and as a result of such location of the heavy portion of the engine-frame the various shocks common to the operation of engines of this type are reflected and will not be perceptible to persons riding within the vehicle, and, further, the longitudinal adjustment of the engine relative to the vehicle-body may be effected without disturbing to any perceptible degree the original distribution of weight of the engine relative to the vehicle-body.

In order to protect the engine from dirt and moisture, we provide the inclosing casing, which consists of the body portion 49,

removable cover 50, and removable side plates '51, Fig. 8. The construction of the inclosing casing is such that oil introduced into the casing will not be thrown out of the casing, and to effect this result we provide this casing with oil-proof joints where openings occur and along its edges. To make the oilproof joints, the sides of the casing are turned inward and downward, as shown at 52, Fig. 6, and the cover of the casing is provided with similar flanges 53. At the lower end of the casing where it is recessed to provide room for the sprocket-gear 17 the sides of the casing are packed around the crank-shaft 14 by means of the half-rings 54 and half-rings 55. Suitable packing material 56 is located within these rings. The half-rings 54 55 and side plates 51 are arranged in guides in thesides of the recessed portion of the body of the casing. As shown in Fig. l, the air and water pumps 32 33 are located within the easing, but have their valves exterior to the casing. The connection between the valves and the pump-cylinders is effected by means of the packing-rings 57 and the threaded tubular coupling 58. The joint at the side of the casing around the rod which operates the links 28 is packed as follows: The sides of the casing are turned outward and backward to form the flanges 59, and located over the rod and provided with the inwardly-extending flanges 60 is a detachable piece 61, which when inserted is passed downward over the rod and has its upper surface flush with the top of the flange 52 of the casing. The top of the casing is secured to the bodybymeaus of plates 62 63 and screws 64.

Located within the casing at the bottom is a body of oil 65, the top of which is arranged to be level with the under surface of the bearings 18 and the lower lip of the opening of the siphon 66 in the oil-case. It will be understood that if any water accumulates from condensed steam within the casing it will pass up the siphon 66 and be discharged without the casing. The rapid movement of the engine-cranks in the body of oil within the cylinder serves to throw the oil all over the working parts of the engine within thecasing, and thus effectually lubricate the en-' gine.

67 indicates the pump-valves, which, it will be observed, are located external to the casing and considerably above the bottom of the pump-cylinder. We make this disposition of these valves, as we find by so doing we can readily pump very hot water and entirely irrespective of the speed of operation of the pump-piston.

68 indicates the regulating-valve for the air-pump, also located external to the casing.

-Projecting from the valve-chest 11 are the ears 69. These ears form a bearing for the rod 70, to which is connected the lever 31,v which operates the links 28.

Having thus described our invention, we claim- 1. In combination with an engine-frame carrying an air-pump and a water-pump, an inclosing oil-case for said frame and pumps, valves for said pumps external to said casing, and means interposed between said valves and pumps for connecting said valves and pumps and preventing the escape of oil from the interior of the casing.

2. A casing for a steam-engine frame, comprising a body portion provided with the flanges 52, packing-rings 54,55, side plates 51, and cover having the flanges 53.

3. In combination with a vehicle-body, a steammotor device suspended at an angle below the body, a casing for said motor device, and a body of oil carried in said casing.

4. The combination with a motor-vehicle, of a two-cylinder reciprocating engine suspended at an angle below said vehicle-body,
